(A) if the Company or any Restricted Subsidiary has Incurred any Indebtedness since the beginning of such period that remains outstanding or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, or both, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving effect on a pro forma basis to such Indebtedness and the use of the proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had been applied as of such date; provided, however, that the pro forma calculation of Consolidated Interest Expense shall not give effect to any Indebtedness Incurred on the date of determination pursuant to Section 4.03(b);

(B) if the Company or any Restricted Subsidiary has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of such period or if any Indebtedness is to be repaid, repurchased, defeased or otherwise discharged on the date of the transaction giving rise to the need to calculate the Consolidated Coverage Ratio, then EBITDA and Consolidated Interest Expense for such period shall be calculated on a pro forma basis as if such discharge had occurred on the first day of such period and as if the Company or such Restricted Subsidiary had not earned the interest income actually earned (if any) during such period in respect of cash or Temporary Cash Investments used to repay, repurchase, defease or otherwise discharge such Indebtedness; provided, however, that the pro forma calculation of Consolidated Interest Expense shall not give effect to the discharge on the date of determination of any Indebtedness to the extent such discharge results from the proceeds of Indebtedness Incurred pursuant Section 4.03(b);

(C) if, since the beginning of such period, the Company or any Restricted Subsidiary shall have made any Asset Disposition, then EBITDA for such period shall be reduced by an amount equal to EBITDA (if positive) directly attributable to the assets which were the subject of such Asset Disposition for such period, or increased by an amount equal to EBITDA (if negative) directly attributable thereto for such period, and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale), and interest income in respect of cash or Temporary Cash Investments received in connection with such Asset Disposition and not otherwise used (or required to be used) either to make a subsequent Investment or

to purchase, repay, redeem or repurchase Indebtedness, shall be calculated on a pro forma basis as if such Asset Disposition had occurred on the first day of such period, with such cash or Temporary Cash Investments being deemed to have earned interest income at the same average rate as the Company’s and the Restricted Subsidiaries’ cash and Temporary Cash Investments actually earned interest over the period for which pro forma effect is being given;

(E) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) shall have made any Asset Disposition, any Investment or acquisition of assets that would have required an adjustment pursuant to clause (C) or (D) above if made by the Company or a Restricted Subsidiary during such period, then EBITDA and Consolidated Interest Expense for such period shall be calculated after giving pro forma effect thereto as if such Asset Disposition, Investment or acquisition had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to an event, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Company.

If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof).

The Consolidated Interest Expense attributable to interest on any Indebtedness under a revolving credit facility the outstanding principal balance of which is required to be computed on a pro forma basis in accordance with the foregoing shall be computed based upon the average daily balance of such Indebtedness during the applicable period, provided, however, that such average daily balance shall be reduced by the amount of any repayment of Indebtedness under such revolving credit facility during the applicable period, to the extent such repayment permanently reduced the commitments or amounts available to be borrowed under such facility.

(B) the net loss of any such Restricted Subsidiary for such period shall be included in determining such Consolidated Net Income;

SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced.

SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation and those described in this Section as not

outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security, but, in certain circumstances, Section 11.06 provides that certain Securities shall be disregarded.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code).

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall advise the Trustee in writing of any change in any “CUSIP” numbers, ISINs or “Common Code” numbers applicable to the Securities.

If a redemption is subject to satisfaction of one or more conditions precedent, the redemption date may be delayed up to 10 Business Days; provided that if such conditions precedent are not satisfied within 10 Business Days of the proposed redemption date, such redemption shall not occur and the notice thereof shall be rescinded. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the notice, plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date), and such Securities shall be canceled by the Trustee.

Principal and interest shall be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due.

The Company shall pay interest on overdue principal at the rate specified therefor in the Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

SECTION 4.02. SEC Reports. Whether or not the Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall file with or furnish to the SEC, as applicable, subject to the next sentence, and provide the Trustee and Securityholders with, such annual and other reports as are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation subject to such Sections (but without exhibits in the case of reports provided to Holders), such reports to be so filed and provided at the times specified for the filings of such reports under such Sections (after giving effect to all applicable extensions and cure periods) and containing all the information, audit reports and exhibits required for such reports.

If, at any time, the Company is not subject to the periodic reporting requirements of the Exchange Act for any reason, the Company shall nevertheless continue filing the reports specified in the preceding sentence with the SEC within such time periods unless the SEC will not accept such a filing. The Company agrees that it will not take any action for the purpose of causing the SEC not to accept such filings. If, notwithstanding the foregoing, the SEC will not accept such filings for any reason, the Company will post the reports specified in the preceding sentence on its website within the time periods (after giving effect to all applicable extensions and cure periods) that would apply if the Company were required to file those reports with the SEC.

Notwithstanding anything to the contrary contained in the immediately preceding paragraph, if the Company is not required to file reports with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, (i.e., is a “voluntary filer”), the reports described in the preceding paragraph shall not be required to contain certain disclosures relating to the Company’s controls and procedures, corporate governance, code of ethics, director independence, market for the Company’s equity securities and executive compensation.

At any time that any of the Company’s Subsidiaries are Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

In addition, the Company shall furnish to the Holders of the Securities and to prospective investors, upon the requests of such Holders, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Securities are not freely transferable under the Securities Act.

The Company also shall comply with the other provisions of Trust Indenture Act § 314(a).

The Company shall be deemed to have furnished such reports to the Trustee and the Holders of the Securities if it has filed such reports with the SEC using the EDGAR (or any successor) filing system and such reports are publicly available through such filing system.

In the event that any direct or indirect parent company of the Company becomes a guarantor of the Securities, the Company may satisfy its obligations under this covenant by furnishing financial information relating to such parent; provided, however, that (a) such financial statements are accompanied by consolidating financial information for such parent, the Company, the Subsidiary Guarantors and the Subsidiaries of the Company that are not Subsidiary Guarantors in the manner prescribed by the SEC and (b) such parent is not engaged in any business in any material respect other than incidental to its ownership, directly or indirectly, of the Capital Stock of the Company.

(1) as promptly as reasonably practicable after filing with the SEC or posting the annual and quarterly reports required by the first paragraph of this Section 4.02, hold a conference call to discuss such reports and the results of operations for the relevant reporting period; and

(2) issue a press release to the appropriate nationally recognized wire services prior to the date of the conference call required to be held in accordance with clause (1) of this paragraph, announcing the time and date of such conference call and including all information necessary to access the call.

This covenant shall be deemed not to impose any duty on the Company under the Sarbanes-Oxley Act of 2002 and the related SEC rules that would not otherwise be applicable.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

SECTION 4.03. Limitation on Indebtedness. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness; provided, however, that the Company and the Subsidiary Guarantors shall be entitled to Incur Indebtedness if, on the date of such Incurrence and after giving effect thereto on a pro forma basis, the Consolidated Coverage Ratio exceeds 2.00 to 1.00.

(b) Notwithstanding the foregoing paragraph (a), the Company and the Restricted Subsidiaries shall be entitled to Incur any or all of the following Indebtedness:

(2) Indebtedness owed to and held by the Company or a Restricted Subsidiary; provided, however, that (A) any subsequent issuance or transfer of any Capital Stock which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any subsequent transfer of such Indebtedness (other than to the Company or a Restricted Subsidiary) shall be deemed, in each case, to constitute the Incurrence of such Indebtedness by the obligor thereon, (B) if the Company is the obligor on such Indebtedness, unless such Indebtedness is owing to a Subsidiary Guarantor, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations with respect to the Securities and (C) if a Subsidiary Guarantor is the obligor on such Indebtedness, unless such Indebtedness is owing to the Company or another Subsidiary Guarantor, such Indebtedness is expressly subordinated to the prior payment in full in cash of all obligations of such Subsidiary Guarantor with respect to its Subsidiary Guarantee;

(3) the Securities (including the Exchange Securities issued in exchange therefor but excluding any Additional Securities) and all Subsidiary Guarantees thereof;

(4) Indebtedness outstanding on the Issue Date (other than Indebtedness described in clause (1), (2) or (3) of this Section 4.03(b));

Indebtedness shall be Incurred only by such Restricted Subsidiary or, so long as such Restricted Subsidiary has no liability with respect to such Refinancing Indebtedness, by the Company or by a Subsidiary Guarantor;

(7) Hedging Obligations consisting of Interest Rate Agreements related to Indebtedness outstanding on the Issue Date or permitted to be Incurred by the Company and its Restricted Subsidiaries pursuant to this Indenture;

(11) Indebtedness consisting of any Guarantee by the Company or a Subsidiary Guarantor of Indebtedness outstanding on the Issue Date or permitted by this Indenture to be incurred by the Company or a Subsidiary Guarantor; provided, however, that if the Indebtedness being guaranteed is subordinated to the Securities or a Subsidiary Guarantee, then the Guarantee thereof shall be subordinated to at least the same extent as the Indebtedness being Guaranteed;

(12) Purchase Money Indebtedness of the Company or a Restricted Subsidiary Incurred to finance the purchase, lease or improvement of property (real or personal), and any Refinancing Indebtedness Incurred to Refinance such Indebtedness, in an aggregate principal amount which, when added together with the amount of Indebtedness Incurred pursuant to this clause (12) and then outstanding, does not exceed the greater of (i) $75.0 million and (ii) 4.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of such Incurrence;

(c) Notwithstanding the foregoing, neither the Company nor any Subsidiary Guarantor shall Incur any Indebtedness pursuant to Section 4.03(b) if the proceeds thereof are used, directly or indirectly, to Refinance any Subordinated Obligations of the Company or any Subsidiary Guarantor unless such Indebtedness shall be subordinated to the Securities or the applicable Subsidiary Guarantee to at least the same extent as such Subordinated Obligations.

(d) For purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness (or any portion thereof) meets the criteria of more than one of the types of Indebtedness described herein, the Company, in its sole discretion, shall classify such item of Indebtedness (or any portion thereof) at the time of Incurrence and shall only be required to include the amount and type of such Indebtedness in one of the above clauses and the Company shall be entitled to divide and classify and reclassify from time to time an item of Indebtedness in more than one of the types of Indebtedness described herein.

Notwithstanding any other provision of this Indenture, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may Incur pursuant to this Indenture shall be deemed not to be exceeded and all other covenants, limitations and ratios in this Indenture be deemed not to be breached or exceeded, solely as a result of fluctuations in exchange rates or currency values.

(B) to the extent the Company so elects, to acquire Additional Assets or make capital expenditures in the Oil and Gas Business within one year (or in the case of an Asset Disposition by, or of the Capital Stock of, Grizzly Holdings, two years) from the later of the date of such Asset Disposition or the receipt of such Net Available Cash; and

(C) to the extent of the balance of the amount of Net Available Cash after application in accordance with clauses (A) and (B), or, if the Company so elects, at any earlier time, to make an offer to the holders of the Securities (and to holders of other Senior Indebtedness of the Company or a Subsidiary Guarantor designated by the Company) to purchase Securities (and such other Senior Indebtedness) pursuant to and subject to the conditions contained in this Indenture;

provided, however, that in connection with any prepayment, repayment, purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness pursuant to clause (A) or (C) above (other than Indebtedness outstanding pursuant to Section 4.03(b)(1), the Company or such Subsidiary shall permanently retire such Indebtedness and shall cause the related loan commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, purchased or otherwise retired.

Notwithstanding the foregoing provisions of this Section 4.06, the Company and such Subsidiaries shall not be required to apply any amount of Net Available Cash in accordance with this Section 4.06 except to the extent that the aggregate amount of Net Available Cash from all Asset Dispositions which is not applied in accordance with this Section 4.06 exceeds $25.0 million.

Pending application of any amount of Net Available Cash pursuant to this Section 4.06, such amount may be invested in any manner not prohibited by this Indenture, including to temporarily reduce revolving credit indebtedness.

For the purposes of Section 4.06(a)(2), the following are deemed to be cash or cash equivalents: (i) the release of, pursuant to a novation or other agreement, or the discharge of, the Company or such Subsidiary from all liability on Indebtedness in connection with such Asset Disposition; (ii) with respect to any Asset Disposition of Hydrocarbon and Mineral Properties, any agreement by the transferee (or an Affiliate thereof) to pay all or a portion of the Company’s or a Restricted Subsidiary’s share of any costs or expenses related to the exploration, development, completion or production of Hydrocarbon and Mineral Properties and activities related thereto; and (iii) any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within 90 days after the Asset Disposition, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion.

The requirement of Section 4.06(a)(3)(B) shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Company or such Subsidiary (or any Restricted Subsidiary) within the time period specified in such clause and the amount of such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

Notwithstanding the foregoing, in the event that a Subsidiary that is not a Wholly Owned Subsidiary effects an Asset Disposition and dividends or distributes to all of its stockholders (including the Company or a Restricted Subsidiary) on a pro rata basis any Net Available Cash from such Asset Disposition, the Company or such Restricted Subsidiary need only apply an amount equal to its pro rata share of such Net Available Cash in accordance with Section 4.06(a)(3) above.

(b) In the event of an Asset Disposition that requires the purchase of Securities (and other Senior Indebtedness of the Company or a Subsidiary Guarantor) pursuant to Section 4.06(a)(3)(C), the Company shall make such offer to purchase Securities on or before the 366^th day (or in the case of an Asset Disposition by, or of the Capital Stock of, Grizzly Holdings, the 731st day) after the later of the date of such Asset Disposition or the receipt of such Net Available Cash and will purchase Securities tendered pursuant to an offer (an “Asset Disposition Offer”) by the Company for the Securities (and such other Senior Indebtedness) at a purchase price of 100% of their principal amount (or, in the event such other Senior Indebtedness was issued with significant original issue discount, 100% of the accreted value thereof) without premium, plus accrued but unpaid interest, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date (or, in respect of such other Senior Indebtedness, such lesser price, if any, as may be provided for by the terms of such Senior Indebtedness) in accordance with the procedures (including prorating in the event of oversubscription) set forth in Section 4.06(c). If the aggregate purchase price of the securities tendered exceeds the Net Available Cash allotted to their

purchase, the Company will select the securities to be purchased on a pro rata basis but in round denominations, which in the case of the Securities will be denominations of $2,000 principal amount or any greater multiple of $1,000. The Company shall not be required to make such an offer to purchase Securities (and other Senior Indebtedness) pursuant to this Section 4.06 if the amount of Net Available Cash available therefor is less than $25.0 million (which lesser amount shall be carried forward for purposes of determining whether such an offer is required with respect to the Net Available Cash from any subsequent Asset Disposition). Upon completion of such an offer to purchase, Net Available Cash shall be deemed to be reduced by the aggregate amount of such offer.

(c) (1) Promptly, and in any event within 10 days after the Company becomes obligated to make an Asset Disposition Offer, the Company shall deliver to the Trustee, and cause to be sent to each Holder, a written notice stating that the Holder may elect to have its Securities purchased by the Company either in whole or in part (subject to prorating as described in Section 4.06(b) in the event the Asset Disposition Offer is oversubscribed) in denominations of $2,000 of principal amount or any greater integral multiple of $1,000 thereof, at the applicable purchase price. The notice shall specify a purchase date not less than 30 days nor more than 60 days after the date of such notice (the “Purchase Date”) and shall contain such information concerning the business of the Company which the Company in good faith believes will enable such Holders to make an informed decision (which at a minimum will include (A) the most recently filed Annual Report on Form 10-K (including audited consolidated financial statements) of the Company, the most recent subsequently filed Quarterly Report on Form 10-Q and any Current Report on Form 8-K of the Company filed subsequent to such Quarterly Report, other than Current Reports describing Asset Dispositions otherwise described in the offering materials (or corresponding successor reports), (B) a description of material developments in the Company’s business subsequent to the date of the latest of such Reports, and (C) if material, appropriate pro forma financial information) and all instructions and materials necessary to tender Securities pursuant to the Offer, together with the information contained in clause (3).

(2) Not later than the date upon which written notice of an Asset Disposition Offer is delivered to the Trustee as provided below, the Company shall deliver to the Trustee an Officers’ Certificate as to (A) the amount of the Offer (the “Offer Amount”), including information as to any other Senior Indebtedness included in the Asset Disposition Offer, (B) the allocation of the Net Available Cash from the Asset Dispositions pursuant to which such Asset Disposition Offer is being made and (C) the compliance of such allocation with the provisions of Section 4.06(a) and (b). On such date, the Company shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust) in Temporary Cash Investments, maturing on the last day prior to the Purchase Date or on the Purchase Date if funds are immediately available by open of business, an amount equal to the Offer Amount to be held for payment in accordance with the provisions of this Section. If the Asset Disposition Offer includes other Senior Indebtedness, the deposit described in the preceding sentence may be made with any other paying agent pursuant to arrangements satisfactory to the Trustee.

Upon the expiration of the period for which the Asset Disposition Offer remains open (the “Offer Period”), the Company shall deliver to the Trustee for cancellation the Securities or portions thereof which have been properly tendered to and are to be accepted by the Company. The Trustee shall, on the Purchase Date, mail or deliver payment (or cause the delivery of payment) to each tendering Holder in the amount of the purchase price. In the event that the aggregate purchase price of the Securities delivered by the Company to the Trustee is less than the Offer Amount applicable to the Securities, the Trustee shall deliver the excess to the Company immediately after the expiration of the Offer Period for application in accordance with this Section 4.06.

(3) Holders electing to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the Purchase Date. Holders shall be entitled to withdraw their election if the Trustee or the Company receives, not later than one Business Day prior to the Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Security purchased. Holders whose Securities are purchased only in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered.

(4) At the time the Company delivers Securities to the Trustee which are to be accepted for purchase, the Company shall also deliver an Officers’ Certificate stating that such Securities are to be accepted by the Company pursuant to and in accordance with the terms of this Section. A Security shall be deemed to have been accepted for purchase at the time the Trustee, directly or through an agent, mails or otherwise sends or delivers payment therefor to the surrendering Holder.

(d) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.06. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 4.06, the Company shall comply with the applicable securities laws and regulations and shall be deemed not to have breached its obligations under this Section 4.06 by virtue of its compliance with such securities laws or regulations.

Notwithstanding anything to the contrary in this Section 4.06, all references herein to “Net Available Cash” shall be deemed to mean cash in an amount equal to the amount of Net Available Cash but not necessarily the actual cash received from the relevant Asset Disposition. The Company and its Subsidiaries shall have no obligation to segregate, trace or otherwise identify Net Available Cash (other than the amount thereof), it being agreed that cash is fungible and that the Company’s obligations under this covenant may be satisfied by the application of funds from other sources.

SECTION 4.07. Limitation on Affiliate Transactions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, enter into any transaction (including the purchase, sale, lease or exchange of any property, employee compensation arrangements or the rendering of any service) with (which term, for purposes of this Section 4.07, shall include “for the benefit of” where appropriate in the context) any Affiliate of the Company involving aggregate consideration in excess of $1.0 million (an “Affiliate Transaction”) unless:

(1) the terms of the Affiliate Transaction, taken as a whole, are no less favorable to the Company or such Restricted Subsidiary than those that could reasonably be expected to be obtained at the time of the Affiliate Transaction in arm’s-length dealings with a Person who is not an Affiliate;

(2) if such Affiliate Transaction involves an amount in excess of $20.0 million, the terms of the Affiliate Transaction are set forth in writing and an officer of the Company disinterested with respect to such Affiliate Transaction shall have determined in good faith that the criteria set forth in Section 4.07(a)(1) are satisfied and shall have approved the relevant Affiliate Transaction as evidenced by an Officers’ Certificate delivered to the Trustee stating that such Affiliate Transaction complies with this Indenture;

(3) if such Affiliate Transaction involves an amount in excess of $50.0 million, the terms of the Affiliate Transaction are set forth in writing and a majority of the members of the Board of Directors of the Company disinterested with respect to such Affiliate Transaction shall have determined in good faith that the criteria set forth in clause (1) are satisfied and shall have approved the relevant Affiliate Transaction, all as evidenced by a resolution of the Board of Directors; and

(4) if such Affiliate Transaction involves an amount in excess of $100.0 million, the Board of Directors shall have received a written opinion from an Independent Qualified Party to the effect that such Affiliate Transaction is fair, from a financial standpoint, to the Company and its Restricted Subsidiaries or is not less favorable to the Company and its Restricted Subsidiaries than could reasonably be expected to be obtained at the time in an arm’s-length transaction with a Person who was not an Affiliate.

(1) any Investment or other Restricted Payment (or any other payments excluded from such definitions or their component definitions), in each case not prohibited to be made pursuant to Section 4.04;

(2) any issuance of securities, or other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment and consulting arrangements, stock options and stock ownership plans or other benefit plans approved by the Board of Directors;

(4) reasonable fees, compensation and other benefits paid to, severance arrangements with, and indemnity and similar arrangements provided on behalf of, officers, directors, employees and consultants of the Company or any Restricted Subsidiary of the Company as determined in good faith by the Company’s Board of Directors or senior management;

(5) any transaction with the Company, a Restricted Subsidiary or joint venture or other Person (other than an Unrestricted Subsidiary) that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns, directly or indirectly, an equity interest in or otherwise controls such Restricted Subsidiary, joint venture or other Person; provided that no Affiliate of the Company, other than the Company or a Restricted Subsidiary, shall have a beneficial interest or otherwise participate in such Restricted Subsidiary, joint venture or other Person other than through such Affiliate’s ownership of the Company;

(6) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company and the granting of customary registration rights in connection therewith;

(7) any transaction with Affiliates pursuant to or contemplated by any agreement that is described in the Offering Circular and any amendments, renewals or extensions of any such agreement (so long as such amendments, renewals or extensions are not materially less favorable to the Company or the Restricted Subsidiaries, taken as a whole, than the agreement so amended, renewed or extended) and all transactions pursuant thereto or contemplated thereby;

(8) transactions with customers, clients, vendors, suppliers or other purchasers or sellers of goods or services, in each case, in their capacities as such and in the ordinary course of business (including pursuant to joint venture agreements);

(9) any transaction on arm’s-length terms with any non-Affiliate that becomes an Affiliate as a result of such transaction;

(11) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that a director or manager of such Person is also a

director or manager of the Company or a Restricted Subsidiary if such director or manager abstains from voting as a director or manager of the Company or such Restricted Subsidiary, as applicable, on such transaction;

(12) pledges by the Company or any Restricted Subsidiary of (or any guarantee by the Company or any Restricted Subsidiary limited in recourse solely to) Equity Interests in Unrestricted Subsidiaries for the benefit of lenders or other creditors of the Unrestricted Subsidiaries; and

(13) agreements of the types described in the defined term “Permitted Business Investments,” contracts for exploring for, drilling, developing, producing, processing, gathering, transporting, marketing or storing Hydrocarbons and Minerals or activities or services reasonably related or ancillary thereto, and other operational contracts, that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any of its Restricted Subsidiaries with unrelated third parties, or if neither the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, then on terms no less favorable than those available from third parties on an arm’s length basis, in each case as determined in good faith by the Company, and all transactions pursuant to or contemplated by such agreements and contracts.

SECTION 4.08. Limitation on Line of Business. The Company shall not, and shall not permit any Restricted Subsidiary to, engage in any business other than a Related Business, except to the extent that such business would not be material to the Company and its Restricted Subsidiaries, taken as a whole.

SECTION 4.09. Change of Control. (a) Upon the occurrence of a Change of Control, each Holder shall have the right to require that the Company repurchase such Holder’s Securities at a purchase price in cash equal to 101% of the principal amount thereof on the date of purchase plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(b) Within 30 days following any Change of Control, the Company shall send a notice to each Holder with a copy to the Trustee (the “Change of Control Offer”) stating:

(1) that a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Securities at a purchase price (the “Change of Control Purchase Price”) in cash equal to 101% of the principal amount thereof on the date of purchase, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date);

(2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization, in each case after giving effect to such Change of Control);

(c) Holders electing to have a Security purchased will be required to surrender the Security, with an appropriate form duly completed, to the Company at the address specified in the notice at least three Business Days prior to the purchase date. Holders will be entitled to withdraw their election if the Trustee or the Company receives, not later than one Business Day prior to the purchase date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and a statement that such Holder is withdrawing its election to have such Security purchased.

(d) On the purchase date, all Securities purchased by the Company under this Section shall be delivered by the Company to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest, if any, to the Holders entitled thereto.

(e) Notwithstanding the foregoing provisions of this Section, the Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer or if notice of redemption has been given pursuant to paragraph 6 of the Securities.

(f) Notwithstanding any other provision of this Indenture, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(g) The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section, the Company shall comply with the applicable securities laws and regulations and shall be deemed not to have breached its obligations under this Section by virtue of its compliance with such securities laws or regulations.

(h) In the event that Holders of not less than 90% in aggregate principal amount of the outstanding Securities accept a Change of Control Offer and the

Company (or any third party making such Change of Control Offer in lieu of the Company as described above) purchases all of the Securities tendered by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Securities that remain outstanding following such purchase at a redemption price equal to the Change of Control Purchase Price, including interest to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

SECTION 4.10. Limitation on Liens. The Company shall not, and shall not permit any Subsidiary Guarantor to, directly or indirectly, Incur or permit to exist any Lien (the “Initial Lien”) of any nature whatsoever on any of its properties (including Capital Stock of a Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, securing any Indebtedness, other than Permitted Liens, without effectively providing that the Securities or such Subsidiary Guarantor’s Subsidiary Guarantee , as applicable, shall be secured equally and ratably with (or, at the Company’s election, prior to) the Indebtedness so secured for so long as such Indebtedness is so secured.

Any such Lien thereby created securing the Securities or any Subsidiary Guarantee pursuant to the preceding sentence shall be automatically and unconditionally released and discharged upon (i) the release and discharge of each Initial Lien to which it relates, (ii) in the case of such Lien securing any such Subsidiary Guarantee, the termination and discharge of such Subsidiary Guarantee in accordance with this Indenture or (iii) any sale, exchange or transfer to any Person not an Affiliate of the Company of the property or assets secured by such Initial Lien.

SECTION 4.11. Future Subsidiary Guarantors. The Company shall cause each Restricted Subsidiary that enters into a Guarantee of any Indebtedness of the Company or any other Restricted Subsidiary (other than a Foreign Subsidiary that Guarantees only Indebtedness Incurred by a Foreign Subsidiary) to, in each case, within 30 days thereafter, execute and deliver to the Trustee a Guaranty Agreement pursuant to which such Restricted Subsidiary will Guarantee payment of the Securities on the same terms and conditions as those set forth in Article 10 of this Indenture and applicable to the other Subsidiary Guarantors.

SECTION 4.12. Compliance Certificate. (a) The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default and whether or not the signers know of any Default that occurred during such period. If they do, the certificate shall describe the Default, its status and what action the Company is taking or proposes to take with respect thereto. Such Officers’ Certificate shall comply with Trust Indenture Act § 314(a)(4).

(b) So long as any of the Securities are outstanding, the Company shall deliver to the Trustee, within 30 days after the occurrence of a Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default, its status, and what action the Company is taking or proposes to take with respect thereto.

SECTION 4.13. Further Instruments and Acts. Upon request of the Trustee, the Company shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 4.14. Waiver of Stay or Extension Laws. The Company (to the extent it may lawfully do so) shall not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture. The Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and shall not hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law had been enacted.

(1) the Securities have an Investment Grade Rating from both Standard & Poor’s and Moody’s;

(3) the Company has delivered to the Trustee the Officers’ Certificate described below,

the covenants listed below will be permanently terminated and the Company and its Subsidiaries, as applicable, will not be subject to the provisions of Sections 4.03, 4.04, 4.05, 4.06, 4.07, 4.08 and Section 5.01(a)(3). On the Termination Date, the Company will provide an Officers’ Certificate to the Trustee regarding such occurrence. The Trustee shall have no obligation to independently determine or verify if the Termination Date has occurred or notify the Holders of the Termination Date. The Trustee may provide a copy of such Officers’ Certificate to any Holder of the Securities upon written request.

SECTION 5.01. When Company May Merge or Transfer Assets. (a) The Company shall not consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of related transactions, directly or indirectly, all or substantially all its assets to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by an indenture supplemental thereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Securities and this Indenture;

(2) immediately after giving pro forma effect to such transaction (and treating any Indebtedness which becomes an obligation of the Company or a Subsidiary as a result of such transaction as having been Incurred by the Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing;

(3) immediately after giving pro forma effect to such transaction, (x) the Successor Company would be able to Incur an additional $1.00 of Indebtedness pursuant to Section 4.03(a) or (y) the Consolidated Coverage Ratio of the Company or the Successor Company will be equal to or greater than the Consolidated Coverage Ratio of the Company immediately prior to such transaction;

(4) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, together stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture (if any) comply with this Indenture; and

(5) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders will not recognize income, gain or loss for Federal income tax purposes as a result of such transaction and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such transaction had not occurred;

provided, however, that clause (3) will not be applicable to (A) the Company or a Restricted Subsidiary consolidating with, merging into, conveying, transferring or leasing all or part of its assets to the Company or a Subsidiary Guarantor or (B) the Company merging with an Affiliate of the Company solely for the purpose and with the sole effect of reincorporating the Company in another jurisdiction.

For purposes of this Section 5.01(a), the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Restricted Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Restricted Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the assets of the Company; provided, however, that this Section 5.01(a) shall not be applicable to Permitted Grizzly Dispositions.

The Successor Company (if not the Company) shall be the successor to the Company and shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and the predecessor Company, except in the case of a lease, shall be released from the obligation to pay the principal of and interest on the Securities.

For all purposes of this Indenture, Subsidiaries of any Successor Company will, upon any transaction subject to this Section 5.01(a), become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture, and all Indebtedness and Liens of the Successor Company and its Subsidiaries that were not Indebtedness or Liens on property or assets, as the case may be, of the Company and its Subsidiaries immediately prior to such transaction shall be deemed to have been Incurred upon such transaction.

(b) The Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, or convey, transfer or lease, in one transaction or a series of related transactions, all or substantially all of its assets to any Person unless:

(1) the resulting, surviving or transferee Person (if not such Subsidiary) shall be a Person organized and existing under the laws of the jurisdiction under which such Subsidiary was organized or under the laws of the United States of America, or any State thereof or the District of Columbia, and such Person (if not the Company or a Subsidiary Guarantor) shall expressly assume, by a Guaranty Agreement, all the obligations of such Subsidiary, if any, under its Subsidiary Guarantee; provided, however, that this clause (1) shall not apply if such Person is not a Subsidiary of the Company if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations, if any, under Section 4.06 in respect of such transaction;

(2) immediately after giving effect to such transaction or transactions on a pro forma basis (and treating any Indebtedness which becomes an obligation of such Subsidiary as a result of such transaction as having been issued by such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; and

(3) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, together stating that such consolidation, merger or transfer and such Guaranty Agreement, if any, complies with this Indenture.

(5) the Company or any Subsidiary Guarantor fails to comply for 60 days after notice with its other agreements contained in this Indenture;

(6) Indebtedness of the Company, any Subsidiary Guarantor or any Significant Subsidiary is not paid within any applicable grace period after final maturity or is accelerated by the holders thereof because of a default and the total amount of such Indebtedness unpaid or accelerated exceeds $25.0 million;

(7) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(B) consents to the entry of an order for relief against it in an involuntary case;

(8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A) is for relief against the Company or any Significant Subsidiary in an involuntary case;

(B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of its property; or

or any similar relief is granted under any foreign laws and, in each case, the order or decree remains unstayed and in effect for 60 days;

(9) any judgment or decree for the payment of money in excess of $25.0 million above the coverage under applicable insurance policies and indemnities, as to which the relevant insurer or indemnitor has not disclaimed responsibility, is entered against the Company or any Significant Subsidiary, remains outstanding for a period of 60 consecutive days following the entry of such judgment or decree and is not discharged, waived or stayed; or

(10) any Subsidiary Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Subsidiary Guarantee) or any Subsidiary Guarantor denies or disaffirms its obligations under its Subsidiary Guarantee.

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

A Default under clauses (4) and (5) shall not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified after receipt of such notice. Such notice must specify the Default, demand that it be remedied, and state that such notice is a “Notice of Default”.

(a) If an Event of Default (other than an Event of Default specified in Section 6.01(7) or (8) with respect to the Company) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding Securities by notice to the Company and the Trustee, may declare the principal of and accrued but unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal and interest shall be due and payable immediately.

(b) If an Event of Default specified in Section 6.01(7) or (8) with respect to the Company occurs and is continuing, the principal of and interest on all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Securityholders.

(c) The Holders of a majority in principal amount of the Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent thereto.

(d) In the event of a declaration of acceleration of the Securities solely because an Event of Default described in Section 6.01(6) has occurred and is continuing, the declaration of acceleration of the Securities shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to Section 6.01(6) shall be remedied or cured by the Company or such Subsidiary or waived by the holders of the relevant Indebtedness within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Securities would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Securities.

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

(b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default and its consequences except:

(b) a Default arising from the failure to redeem or purchase any Security when required pursuant to this Indenture; or

(c) a Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Securityholder affected.

When a Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly prejudicial to the rights of other Securityholders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

SECTION 6.06. Limitation on Suits. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Securityholder may pursue any remedy with respect to this Indenture or the Securities unless:

(1) such holder has previously given the Trustee notice that an Event of Default is continuing;

(2) holders of at least 25% in principal amount of the outstanding Securities have requested the Trustee to pursue the remedy;

(3) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

(5) holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction inconsistent with such request within such 60-day period.

A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. In the event that the Definitive Securities are not issued to any beneficial owner promptly after the Registrar has received a request from the Holder of a Global Security to issue such Definitive Securities to such beneficial owner of its nominee, the Company expressly agrees and acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture, the right of such beneficial holder of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial holder’s Securities as if such Definitive Securities had been issued.

SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07.

SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Securityholders allowed in any judicial proceedings relative to the Company, its creditors or its property and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07.

SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

SECOND: to Securityholders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

Subject to the requirements of the following sentence, the Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section. At least 15 days before such record date, the Company shall cause to be sent to each Securityholder and the Trustee a notice that states the record date, the payment date and amount to be paid.

SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Securities.

SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s own affairs.

(1) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that:

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the Trust Indenture Act.

SECTION 7.02. Rights of Trustee. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel.

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) To the extent permitted under the Trust Indenture Act, the Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers.

(e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which may be incurred therein or thereby.

(g) The Trustee shall have no duty to inquire as to the performance of the Company’s covenants in Article 4. In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default except: (i) any Event of Default occurring pursuant to Section 6.01(1) or 6.01(2); or (ii) any Default or Event of Default of which a Trust Officer shall have received written notification.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

SECTION 7.05. Notice of Defaults. If a Default occurs, is continuing and is known to the Trustee, the Trustee shall send to each Securityholder notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of or interest on any Security (including payments pursuant to the mandatory purchase provisions of such Security), the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is not opposed to the interests of the Securityholders.

SECTION 7.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with May 15, 2016, and in any event prior to July 15 in each year, the Trustee shall mail to each Securityholder a brief report dated as of May 15 that complies with Trust Indenture Act § 313(a). The Trustee also shall comply with Trust Indenture Act § 313(b).

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof.

SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its services. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company shall indemnify the Trustee against any and all loss, liability or expense (including attorneys’ fees) incurred by it in connection with the administration of this trust and the performance of its duties hereunder. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee that has been adjudicated to have been the result of the Trustee’s own wilful misconduct, negligence or bad faith.

To secure the Company’s payment obligations in this Section, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

The Company’s payment obligations pursuant to this Section shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(7) or (8) with respect to the Company, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

(a) The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the outstanding Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee.

(c) If the Trustee resigns, is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

(d) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07.

(e) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

(f) If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(g) Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s obligations under Section 7.07 shall continue for the benefit of the retiring Trustee.

(a) If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

(b) In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have.

SECTION 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Trust Indenture Act § 310(a). The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in Trust Indenture Act § 310(b)(1) are met.

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act § 311(a) to the extent indicated.

SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a) When (1) the Company delivers to the Trustee all outstanding Securities (other than Securities replaced pursuant to Section 2.07) for cancellation or (2) all outstanding

Securities have become due and payable, whether at maturity or on a redemption date as a result of the sending of a notice of redemption pursuant to Article 3 hereof and, in the case of clause (2), the Company irrevocably deposits with the Trustee funds sufficient to pay at maturity or upon redemption all outstanding Securities, including interest thereon to maturity or such redemption date (other than Securities replaced pursuant to Section 2.07), and if in either case the Company pays all other sums payable hereunder by the Company, then this Indenture shall, subject to Section 8.01(c), cease to be of further effect. The Trustee shall acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company.

(b) Subject to Sections 2.03, 2.06, 2.07, 8.01(c) and 8.02, the Company at any time may terminate (1) all its obligations under the Securities and this Indenture (“legal defeasance option”) or (2) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10 and 4.11 and the operation of Sections 6.01(6), 6.01(7), 6.01(8), 6.01(9) and 6.01(10) (but, in the case of Sections 6.01(7) and (8), with respect only to Subsidiaries) and the limitations contained in Section 5.01(a)(3) (“covenant defeasance option”).

The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of Default with respect thereto. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Sections 6.01(4), 6.01(6), 6.01(7), 6.01(8) and 6.01(9) (but, in the case of Sections 6.01(7) and (8), with respect only to Subsidiaries) or because of the failure of the Company to comply with Section 5.01(a)(3). If the Company exercises its legal defeasance option or its covenant defeasance option, each Subsidiary Guarantor shall be automatically released from all of its obligations with respect to its Subsidiary Guarantee.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

(c) Notwithstanding clauses (a) and (b) above, the Company’s obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 7.07 and 7.08 and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.04 and 8.05 shall survive.

SECTION 8.02. Conditions to Defeasance. The Company may exercise its legal defeasance option or its covenant defeasance option only if:

(1) the Company irrevocably deposits in trust with the Trustee (x) cash in United States dollars or (y) cash in United States dollars, U.S. Government Obligations, or a combination thereof, in such amounts as, in the aggregate, will be sufficient (in the case of clause (y), (A) in the opinion of a nationally recognized firm of independent public accountants or a nationally recognized

investment banking firm, or (B) if no such opinion in the immediately preceding clause (A) can be reasonably obtained, in the opinion of the chief financial officer of the Company) for the payment of principal of and interest on the Securities to redemption or maturity, as the case may be;

(2) the Company delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion (or, if two or more nationally recognized firms of independent accountants decline to issue such opinion after the Company has made reasonable efforts to obtain such an opinion, a certificate from the Company’s chief financial officer expressing such opinion) that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay principal and interest when due on all the Securities to maturity or redemption, as the case may be;

(3) 91 days pass after the deposit is made and during the 91-day period no Default specified in Sections 6.01(7) or (8) with respect to the Company occurs which is continuing at the end of the period;

(4) the deposit does not constitute a default under any other agreement binding on the Company (other than a default resulting from the borrowing of funds to be applied to such deposit and any similar concurrent deposit relating to other Indebtedness and, in each case, the granting of any Lien to secure such borrowings in connection therewith);

(5) the Company delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940;

(6) the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred (and, in the case of legal defeasance only, such Opinion of Counsel must be based on a ruling of the Internal Revenue Service or other change in applicable Federal income tax law);

(7) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Securityholders will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit or covenant defeasance and will be subject to

Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit or covenant defeasance had not occurred; and

(8) the Company delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, together stating that all conditions precedent to the defeasance of the Securities as contemplated by this Article 8 have been complied with.

Before or after a deposit, the Company may make arrangements satisfactory to the Trustee for the redemption of Securities at a future date in accordance with Article 3.

SECTION 8.03. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities.

SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them at any time.

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Securityholders entitled to the money must look to the Company for payment as general creditors.

SECTION 8.05. Indemnity for Government Obligations. The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and each Subsidiary Guarantor’s obligations under this Indenture, each Subsidiary Guarantee and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided, however, that, if the Company has made any payment of interest on or principal of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 9.01. Without Consent of Holders. The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture, the Securities and the Subsidiary Guarantees without notice to or consent of any Securityholder:

(2) to provide for the assumption by a successor corporation of the obligations of the Company or any Subsidiary Guarantor under this Indenture as contemplated by Article 5;

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities (provided that the uncertificated Securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Securities are described in Section 163(f)(2)(B) of the Code);

(4) to add Guarantees with respect to the Securities, including any Subsidiary Guarantees, or to secure the Securities;

(5) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit of the Holders of the Securities or to surrender any right or power conferred upon the Company or any Subsidiary Guarantor;

(6) to make any change that does not adversely affect the rights of any holder of the Securities in any material respect;

(7) to comply with any requirement of the SEC in connection with the qualification of this Indenture under the Trust Indenture Act;

(8) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Securities; provided, however, that (a) compliance with this Indenture as so amended would not result in Securities being transferred in violation of the Securities Act or any other applicable securities law and (b) such amendment does not materially and adversely affect the rights of Holders to transfer Securities;

(9) to conform the text of this Indenture, the Securities or the Subsidiary Guarantees to any provision of the “Description of the Notes” section of the Offering Circular to the extent that such provision in the “Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Securities or the Subsidiary Guarantees; or

(10) to reflect the issuance of Additional Securities in compliance with the terms of this Indenture.

After an amendment under this Section becomes effective, the Company shall send to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section.

(a) The Company, the Subsidiary Guarantors and the Trustee may amend this Indenture the Securities or the Subsidiary Guarantees with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities) and any past default or compliance with any provisions may also be waived with the consent of the Holders of at least a majority in principal amount of the Securities then outstanding. However, without the consent of each Securityholder affected thereby, an amendment or waiver may not:

(B) reduce the rate of or extend the time for payment of interest on any Security;

(D) reduce the amount payable upon the redemption of any Security or change the date on which any Security may be redeemed pursuant to paragraph 5 of the Securities (provided that the foregoing shall not include changing the notice periods for any redemption);

(F) impair the right of any holder of the Securities to receive payment of principal of and interest on such holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Securities;

(G) make any change in Section 6.04 or 6.07 or the second sentence of this Section;

(H) make any change in the ranking or priority of any Security that would adversely affect the Securityholders; or

(I) make any change in, or release other than in accordance with this Indenture, any Subsidiary Guarantee that would adversely affect the Securityholders.

(b) It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

(c) After an amendment under this Section becomes effective, the Company shall send to Securityholders a notice briefly describing such amendment. The failure to give such notice to all Securityholders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

(d) Notwithstanding the preceding, (i) the provisions under this Indenture, including Section 4.06, relative to the obligation to make an offer to repurchase the Securities as a result of an Asset Disposition and (ii) the provisions under this Indenture, including Section 4.09, relative to the Company’s obligation to make an offer to repurchase the Securities as a result of a Change of Control, in each case may be waived or modified with the written consent of the holders of a majority in principal amount of the Securities.

SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to this Indenture or the Securities shall comply with the Trust Indenture Act as then in effect.

(a) A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective. After an amendment or waiver becomes effective, it shall bind every Securityholder. An amendment or waiver becomes effective upon the execution of such amendment or waiver by the Trustee.

SECTION 10.01. Guarantees. (a) Subject to the terms and conditions of this Article 10, each Subsidiary Guarantor hereby unconditionally and irrevocably guarantees, jointly and severally, to each Holder and to the Trustee and its successors and assigns (i) the full and punctual payment of principal of and interest on the Securities when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Company under this Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company under this Indenture and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). Each Subsidiary Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor will remain bound under this Article 10 notwithstanding any extension or renewal of any Obligation.

(b) Each Subsidiary Guarantor waives presentation to, demand of, payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person (including any Subsidiary Guarantor) under this Indenture, the Securities or any other agreement or otherwise; (2) any extension or renewal of any

thereof; (3) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (4) the release of any security held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (6) except as set forth in Section 10.06, any change in the ownership of such Subsidiary Guarantor.

(c) Each Subsidiary Guarantor further agrees that its Subsidiary Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(d) Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06, the obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of such Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

(e) Each Subsidiary Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Company or otherwise.

(f) In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Subsidiary Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and (C) all other monetary Guaranteed Obligations of the Company to the Holders and the Trustee.

(g) Each Subsidiary Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations hereby may be accelerated as provided in Article 6 for the purposes of such Subsidiary Guarantor’s Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Subsidiary Guarantor for the purposes of this Section.

(h) Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section.

SECTION 10.02. Limitation on Liability. Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 10.03. Successors and Assigns. This Article 10 shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 10.04. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise.

SECTION 10.05. Modification. No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by any Subsidiary Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 10.06. Release of Subsidiary Guarantor. A Subsidiary Guarantor will be automatically released from its obligations under this Article 10 (other than any obligation that may have arisen under Section 10.07):

(2) upon the disposition of all or a portion of the Capital Stock of such Subsidiary Guarantor such that such Subsidiary Guarantor ceases to be a Subsidiary, if in connection therewith the Company provides an Officers’ Certificate to the Trustee to the effect that the Company will comply with its obligations, if any, under Section 4.06 in respect of such disposition;

(3) upon the designation of such Subsidiary Guarantor as an Unrestricted Subsidiary;

(4) at such time as such Subsidiary Guarantor does not have any Guarantees outstanding that would have required such Subsidiary Guarantor to enter into a Guaranty Agreement pursuant to Section 4.11; or

(5) if the Company exercises its legal defeasance option or its covenant defeasance option in Section 8.01 or if the Company’s obligations under this Indenture are discharged in accordance with the terms of this Indenture.

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that any of the conditions described above has occurred, the Trustee shall execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence the release of any Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Indenture.

The Registrar shall, in accordance with such instructions, instruct the Depository to credit to the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer the beneficial interest in the Global Security being transferred.

(ii) If the proposed transfer is a transfer of a beneficial interest in one Global Security to a beneficial interest in another Global Security, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Security to which such interest is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Global Security from which such interest is being transferred.

(iii) Notwithstanding any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Security may not be transferred as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

(iv) In the event that a Global Security is exchanged for Definitive Securities pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A, Regulation S or another applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(d) Restrictions on Transfer of Temporary Regulation S Global Securities. During the Distribution Compliance Period, beneficial ownership interests in Temporary Regulation S Global Securities may only be sold, pledged or transferred in accordance with the Applicable Procedures and only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange for an interest in a Permanent Regulation S Global Security), or (iii) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities laws of any State of the United States.

(i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Security certificate evidencing the Global Securities (and all Securities issued in exchange therefor or in substitution thereof), in the case of Securities offered otherwise than in reliance on Regulation S shall bear a legend in substantially the following form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (II) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (III) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (IV) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (IV) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

Each certificate evidencing a Security offered in reliance on Regulation S shall, in addition to the foregoing, bear a legend in substantially the following form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S.

SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT.

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security).

(iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global Security, as applicable.

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued

in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated or global form, in each case without the restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

(v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in global form with the global securities legend and the applicable restricted securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange.

(f) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depository for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, a member of, or a participant in the Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or member thereof, with respect to any ownership interest in the Securities or with respect to the delivery to any participant, member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial owners.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depository participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(a) A Global Security deposited with the Depository or with the Trustee as Securities Custodian for the Depository pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Securities in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only if such transfer complies with Section 2.3 hereof and (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security and the Depository fails to appoint a successor depository or if at any time such Depository ceases to be a “clearing agency” registered under the Exchange Act, in either case, and a successor depository is not appointed by the Company within 90 days of such notice (ii) an Event of Default has occurred and is continuing or (iii) the Company, in its sole discretion, notifies the Trustee in writing that it elects to cause the issuance of Definitive Securities under this Indenture.

(b) Any Global Security that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by the Depository to the Trustee located at its principal corporate trust office in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Definitive Securities of authorized denominations. Any portion of a Global Security transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered only in minimum denominations of $2,000 principal amount and any greater integral multiple of $1,000 thereof and registered in such names as the Depository shall direct. Any Definitive Security delivered in exchange for an interest in a Transfer Restricted Security shall, except as otherwise provided by Section 2.3(e) hereof, bear the applicable restricted securities legend and definitive securities legend set forth in Exhibit 1 hereto.

(c) Subject to the provisions of Section 2.1(b) hereof, the registered Holder of a Global Security shall be entitled to grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(d) In the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Company shall promptly make available to the Trustee a reasonable supply of Definitive Securities in definitive, fully registered form without interest coupons. In the event that such Definitive Securities are not issued, the Company expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to Section 6.06 of this Indenture, the right of any beneficial owner of Securities to pursue such remedy with respect to the portion of the Global Security that represents such beneficial owner’s Securities as if such Definitive Securities had been issued.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO.

Gulfport Energy Corporation, a Delaware corporation, promises to pay to , or registered assigns, the principal sum of dollars [(or such greater or lesser amount as may be indicated on the Schedule of Increases or Decreases in Global Security attached hereto)]¹ on May 1, 2023.

Additional provisions of this Security are set forth on the other side of this Security.

Gulfport Energy Corporation, a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of 0.50%) from and including the date on which any such Registration Default shall occur to but excluding the earlier of (x) the date on which all Registration Defaults have been cured and (y) the date on which no Securities are Transfer Restricted Securities. The Company will pay interest semiannually on May 1 and November 1 of each year, commencing November 1, 2015. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from April 21, 2015. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Company will pay interest on overdue principal at the rate borne by this Security plus 1.0% per annum, and it will pay interest on overdue installments of interest at the same rate to the extent lawful.

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the April 15 or October 15 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

Initially, Wells Fargo Bank, N.A., a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

The Company issued the Securities under an Indenture dated as of April 21, 2015, as such may be amended or supplemented from time to time (the “Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms.

The Securities are general unsecured obligations of the Company. The Company shall be entitled, subject to its compliance with Section 4.03 of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture. The Indenture contains covenants that limit the ability of the Company and its subsidiaries to incur additional indebtedness; pay dividends or distributions on, or redeem or repurchase capital stock; make investments; engage in transactions with affiliates; create liens on assets; transfer or sell assets; guarantee indebtedness; restrict dividends or other payments of subsidiaries; and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries. These covenants are subject to important exceptions and qualifications and are subject to termination upon the occurrence of certain events.

Except as set forth below and in Section 4.09(h) of the Indenture, the Company shall not be entitled to redeem the Securities at its option.

On and after May 1, 2018, the Company shall be entitled at its option to redeem all or a portion of the Securities, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on May 1 of the years set forth below:

In addition, any time prior to May 1, 2018, the Company shall be entitled at its option on one or more occasions to redeem Securities (which includes Additional Securities, if any) in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) issued prior to such date at a redemption price (expressed as a percentage of principal amount) of 106.625%, plus accrued and unpaid interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), with an amount equal to the net cash proceeds from one or more Qualifying Equity Offerings; provided, however, that (1) at least 65% of such aggregate principal amount of Securities (which includes Additional Securities, if any) remains outstanding immediately after the occurrence of each such redemption (with Securities held, directly or indirectly, by the Company or its Affiliates being deemed to be not outstanding for purposes of such calculation); and (2) each such redemption occurs within 90 days after the date of the related Qualifying Equity Offering.

Prior to May 1, 2018, the Company shall be entitled, at its option, to redeem all or a portion of the Securities at a redemption price equal to 100% of the principal amount of the Securities plus the Applicable Premium as of, and accrued and unpaid interest to, the redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date).

Notice of redemption shall be sent at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to the redemption date if the notice is issued in connection with a defeasance of the Securities or a satisfaction and discharge of the Indenture. Any inadvertent defect in the notice of redemption, including an inadvertent failure to give notice, to any Holder selected for redemption shall not impair or affect the validity of the redemption of any other Security redeemed in accordance with the provisions of the Indenture. Securities in denominations larger than $2,000 principal amount may be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the redemption price of and accrued interest on all Securities (or portions thereof) to be redeemed on the redemption date is deposited with the Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after such date interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

Notice of any redemption in connection with any Qualifying Equity Offering or other securities offering or any other financing, or in connection with a transaction (or a series of related transactions) that constitute a Change of Control, may, at the Company’s discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including completion of the related Qualifying Equity Offering, securities offering, financing or Change of Control. If a redemption is subject to satisfaction of one or more conditions precedent, the redemption date may be delayed up to 10 Business Days; provided that if such conditions precedent are not satisfied within 10 Business Days of the proposed redemption date, such redemption shall not occur and the notice thereof shall be rescinded.

Upon a Change of Control, each Holder shall have the right to require the Company to repurchase such Holder’s Securities at a purchase price equal to 101% of the principal amount of the Securities to be repurchased plus accrued interest, if any, to the date of repurchase (subject to the right of holders of record on the relevant record date to receive interest due on the related interest payment date) as provided in, and subject to the terms of, the Indenture.

The Indenture provides that, under certain circumstances, the Company shall be required to use the Net Available Cash from an Asset Disposition to make an offer to Holders to purchase Securities at a purchase price of 100% of their principal amount plus accrued but unpaid interest, subject to the rights of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

The payment by the Company of the principal of, and premium and interest on, the Securities is fully and unconditionally guaranteed on a joint and several senior basis by each of the Subsidiary Guarantors to the extent set forth in the Indenture.

The Securities are in registered form without coupons in denominations of $2,000 principal amount and whole multiples of $1,000 in excess of $2,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 days before a selection of Securities to be redeemed or 15 days before an interest payment date.

The registered Holder of this Security may be treated as the owner of it for all purposes.

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee (x) cash in United States dollars or (y) cash in United States dollars, U.S. Government Obligations, or a combination thereof, in such amounts as, in the aggregate, will be sufficient (in the case of clause (y), (A) in the opinion of a nationally recognized firm of independent public accountants or a nationally recognized investment banking firm, or (B) if no such opinion in the immediately preceding clause (A) can be reasonably obtained, in the opinion of the chief financial officer of the Company) for the payment of principal of and interest on the Securities to redemption or maturity, as the case may be.

Subject to certain exceptions set forth in the Indenture, (a) the Indenture and the Securities may be amended with the written consent of the Holders of at least a majority in principal amount outstanding of the Securities and (b) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount outstanding of the Securities. Subject to certain exceptions set forth in the Indenture, without the consent of any Securityholder, the Company, the Subsidiary Guarantors and the Trustee shall be entitled to amend the Indenture or the Securities to cure any ambiguity, omission, defect or inconsistency, to comply with Article 5 of the Indenture, to provide for uncertificated Securities in addition to or in place of certificated Securities, to add guarantees with respect to the Securities, including Subsidiary Guarantees, to secure the Securities, to add additional covenants or surrender rights and powers conferred on the Company or the Subsidiary Guarantors, to comply with any requirement of the SEC in connection with qualifying the Indenture under the Act, to make any change that does not adversely affect the rights of any Securityholder in any material respect, to make amendments to provisions of the Indenture relating to the transfer and legending of the Securities, to conform the text of the Securities to any provision of the “Description of the Notes” section of the Offering Circular to the extent that such provision in the “Description of the Notes” was intended to be a verbatim recitation of a provision of the Indenture, the Securities or the Subsidiary Guarantees, or to reflect the issuance of Additional Securities.

Under the Indenture, Events of Default include (a) default for 30 days in payment of interest on the Securities; (b) default in payment of principal on the Securities at maturity, upon optional redemption, upon declaration of acceleration or otherwise, or failure by the Company to redeem or purchase Securities when required; (c) failure by the Company to comply with other agreements in the Indenture or the Securities, in certain cases subject to notice and lapse of time; (d) certain accelerations (including failure to pay within any grace period after final maturity) of other Indebtedness of the Company if the amount accelerated (or so unpaid) exceeds $25.0 million; (e) certain events of bankruptcy or insolvency with respect to the Company and the Significant Subsidiaries; (f) certain judgments or decrees for the payment of money in excess of $25.0 million; and (g) certain defaults with respect to Subsidiary Guarantees. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Certain events of bankruptcy or insolvency with respect to the Company are Events of Default that will result in the Securities being due and payable immediately upon the occurrence of such Events of Default.

Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Securityholders notice of any continuing Default (except a Default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

A director, officer, employee, incorporator or stockholder, as such, of the Company or any Subsidiary Guarantor shall not have any liability for any obligations of the Company under the Securities or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. By accepting a Security, each Securityholder waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

This Security shall not be valid until an authorized signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

Customary abbreviations may be used in the name of a Securityholder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Securities and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Securityholders. No representation is made as to the accuracy of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

Each Holder of a Security, by acceptance hereof, acknowledges and agrees to the provisions of the Registration Rights Agreement, including the obligations of the Holders with respect to a registration and the indemnification of the Company to the extent provided therein.

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Upon transfer, the Securities would be registered in the name of the new beneficial owner as follows:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Securities, and we invest in or purchase securities similar to the Securities in the normal course of our business. We, and any accounts for which we are acting, are each able to bear the economic risk of our or its investment.

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is two years after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (i) to the Company, (ii) in the United States to a person whom the seller reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A, (iii) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is an institutional accredited investor purchasing for its own account or for the account of an institutional accredited investor, in each case in a minimum principal amount of the Securities of $250,000, (iv) outside the United States in a transaction complying with the provisions of Rule 904 under the Securities Act, (v) pursuant to an exemption from registration under the Securities Act provided by Rule 144 (if available) or (vi) pursuant to an effective registration statement under the Securities Act, in each of cases (i) through (vi) subject to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (iii) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date of the Securities pursuant to clause (iii), (iv) or (v) above to require the delivery of an opinion of counsel, certifications or other information satisfactory to the Company and the Trustee.
